Ok so it was not the gcc manpage that spoke about the "discouraged"
status, but it was dlopen.3 as of man-pages-3.41:
"""In case you need to avoid linking against the system startup files,
this can be done by using the gcc(1) -nostartfiles command-line option.
Using these routines, or the gcc -nostartfiles or -nostdlib options, is
not recommended. Their use may result in undesired behavior, since the
constructor/destructor routines will not be executed (unless special
measures are taken)."""
But gluster has not provided any reason to me to avoid linking against
crt (the C standard library runtime), nor does the project have a reason
to avoid linking against crt either.
